Re: IBM Model M - Cleaning Membrane. Isopropyl / sterilized water / or?

Alcohol is the best option because it will dissolve grease and whatnot while leaving everything clean afterward. Dish soap and tap water will do the same job with a little more work.

You'll want some very fine sandpaper to clean any oxidized contacts in either case.

Re: Olympia typewriter keyboard review (Mitsumi standard mechanical)

I like the sound. Nice and chunky. Seems like the closest thing in feel might be something like Futaba MD? I kinda wished you'd made some more comparisons besides the SKCM one. Though that switch plate DOES look like it was yanked out of some kind of Alps.

Re: Fortune Systems looooong keyboard with Digitran capacitive switches (conversion)

The pads are the sense. The controller going crazy and had to be shot thing is because you hadn't dialed it in yet and when the whole keyboard is instantaneously sending keypresses at startup, it shuts the input down as a protective measure, but you can still adjust the values. Then once you do and ...

It's just rows to rows and columns to columns. Xwhatsit is already all set up for you if you use one. The Xwhatsit pdf has all the pins labeled. DMA's has way better features but you need to set up the firmware yourself on the raw devboards with PSoC creator. But you can choose what pins do what and...

Digitran are capacitive. You don't need to mess with the PCB at all other than to pull controller parts to fit a new one in.

Good choice, Thomas. I can always count on some quality taste in your reviews.

Re: Resources /guides for beamspring maintenance? Are there any?

Restoration is more important. Check the foam, remove and wipe down the sense PCB with alcohol, open and clean any finicky switches, tune the controller, etc. Once it's restored, the only maintenance you really need is some use parts like a set of selectric caps for daily so you don't use up the ori...

Re: New Beamspring Converters on Ebay

It's usually a timing thing. If you can cut down the timing on the solenoid to minimum, then you won't get any problems at least up to 85wpm. Probably faster, but that's about as high as I can go. I'm not particularly fast. Thomas had the problems in his video because the owner hadn't tuned the sole...

Re: Problems flashing an M110A converter (again)

You can also try AVRDUDESS with the SS. It has a GUI and lets you know if what you selected is detected. I use it for all my pro-micro clone flashes.

Plus it keeps the controller in bootloading mode once detected so you don't have to worry about a few second timer.

If you pulled a capacitor and everything worked fine, then I would just leave it yanked and call it a day. Or go and reflow all the solder joints on the board, put in your replacement cap and see if that fixes it before anything gets more involved. That's pretty much the old "Did you try turning it ...
